ALBERT BROADMEYER, or HARaIsBURG, PENNSYLVANIA, AssIGNoR To W. o. HICKOK MANUFACTURING COMPANY, or HARRISBURG, PENNSYLVANIA, A

CORPORATION OF PENNSYLVANIA.

BULING APPARATUS."

To all whom t may concern Be it known that I, ALBERT BROADMEYER, a citizen of theUnited States Vresiding at Harrisburg, in the county of auphin and State of Pennsylvania, have invented certain new and -useful Improvements in Ruling Apparatus, of ywhich the following is a specification.

The present invention relates more particularly to drying means for ruled paper. It is well understood that it requires some time for the lines to dry after the paper comesl from the ruling mechanism, and it is therefore the custom Vto carry the separate sheets a considerable distance before they are piled, in order to permit the ink to dry and thus avoid smudging of rtheiwork.

The primary object of the present invention is to provide means that will hold the paper flat, thus avoiding its tendency to curl by reason of its dampness Afrom the ink, and avoid danger of displacement from air` currents, thereby keeping it in proper shape and permitting each sheet to be delivered flat. Moreover it permits the use of artiicial currents ofwarm air withoutdanger of displacing the sheets and causing the conveying elements to intersect the lines, and thus smear the ink.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein `Figures 1'A and 1B together constitute a sectional.y view somewhat diagrammatic in its character through a ruling machine, and illustrating the preferred embodiment ofthe drying mechanism. y

F ig. 2 is an end elevation of the same.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment disclosed, suitableA supporting frame Sis employed, on which is mounted a bed plate or 'table 4. The upper face' of this table is convexed in form. An endless conveyer belt 5 hask an upper stretch 6 that moves longitudinally over the table 4, and has a lower return stretch 7.

The belt passes around a rear roller 8 of relatively large'diameterand around a front `Speeication of Letters Patent. Patented Julle 22, 1920.k Application led September 22, 19x19.

Serial No. 325,370.

driving drum or roller 9 actuated by an suitable source of power, not shown. guide roller 10, located in advance of the table 4, serves to hold the portion of the belt in advance of said table in depressed relation so as to'insure that the portion of the conveyer moving over the table is smooth and flat thereon. Supporting rollers 11 are interposed between the roller 9 and roller 10, and serve to maintain the belt between the said rollers 9 and 10 in substantially convexed relation. The lower stretch 7 of the belt is guided by suitable rollers 12, and terminates at a relatively small roller 13 located below1 the driving drum 9. A tension roller 14 is located slightly below and in rear of the drum 9, the belt 5 passing around said roller 14 on the opposite side to the drum 9, as will be clear by reference to Fig. 1A.

Operating overthe upper stretch 6 of the belt 5 are suitable ruling instrumentalities, comprising pens 15 carried by beams 16. It is believed to be unnecessary to go into detail regarding these instrumentalities, as they may be of any well known or desired construction, though preferably of the character disclosed in my co-pending application,

Serial No. 325,368,filed September 22,1919. A suitable gage or gate 17, located over the central of the rollers 11, determines the passage of the sheets tothe ruling devices.

' In order to insurethe proper movement of the ypaper with the beltf 5, endless holding cords or bands 18 have lower stretches that rest upon the outer face of the upper stretch 6 of the belt.y These cords or bands pass around a roller 19 located vabove the drum 9, thencebeneath the roller l() and around a rear roller 20 located above the upper stretch of the belt 6 in advance of the rear roller 8. Suitably elevated guide rollers 21 and 22 support the return upper stretches of the cords or bands, and guides 23 adjustably mounted on a supportingrod 24, determinethe positions of the cords or bands transversely of the belt.

Located in the lower portion of the frame beneath the upper belt 5, is a lower endless belt 25 havingan upper substantially horizontal stretch 26 and a lower return stretch 27. The rear portion of the belt passes around a relatively small roller 225 and a lower roller 29 of larger diameter.Y rlhe Yliront portion oi said belt 25 passes around the iii-ont portion of a guide roller 3() ot relatively large diameter and around a roller 31 placed within the belt and located above the roller B0. nother guide roller 32, disposed in advance ol and below the roller Si), serves as an additional guide .ior the belt 25.

Inter-posed between the lower stretch 7 of the upper belt and the upper stretch 2G of the lower belt 25, are endless holding bands or cords 33, each having an upper stretch 34 extending longitudinally" `along and in coaction with the outer iace of the lower stretch ot the upper belt 7. rllhey also have lower stretches located longitudinally upon and coacting with the upper stretch 2G of the lower belt 25. The cords or bands at their rear ends pass around the roller 8 and around a guide roller 36 located above and slightly in advance of the roller 8. The' rear portions are 'furthermore passed through guides 39 slidably mounted on a supporting rod e0, the guides 39 determining the positions of the cords transversely of the belt. The trout portions of the cords or bands 8f3 pass around the roller 30, being interposed between said roller and the outer 'tace ot the band 25. Their rear portions are 'furthermore guided by a roller 41 located adjacent to the roller 2S, and a guide roller Ll2, located between the roller L11 and the guide roller 12.

The space thus left below the rear portion ot the upper belt 5 and the corresponding portions of the bands or cords is occupied by coacting endless delivery bands 43 carried on pulleys 44, The adjacent coact ing` faces of said bands 43 are substantially in line with 'the coacting stretches 26 -and l5 ot the lower belt and cords or bands.

The operation is substantially as follows. Sheetsotl paper. successively introduced between the rollers 9 and 19, are caught by the coaetingstretches 6 and 18, and when the gage or gate 1T is raised, are passed into the nia/shine and beneath the ruling` instrumentalities which produce the lines thereon. After passing the ruling apparatus, they are released from the cords 18 and are carried by the upper stretch of the belt 6 to the drum S. Here they are engaged between the belt 5 and the cords and are consequently carried around the drum and are held against the under 'face of the lower stretch ot the upper belt 7 by the upper stretches 34 ot the bands or cords 33. They are thus carried back to the frontof the man chine, and it will bc noted that during this portion of: their travel, they are securely held, so that they` are not only maintained lint and against any curling tendency due to the damp ink, but cannot be displaced by air currents or any vibration of the parts. Reaching the front end of the machine, the belt 5 is removed therefrom by passing around the roller 13, but the sheets are immediately might between the belt 25 and the cords 33, and are carried around the roller 30. They are held upon the upper stretch 26 of the belt 25 by the lower stretches 'of the cords or bands 33, and are thus caused to again travel the full length of the machine, but rearwardly, being delivered between the rollers 28 and 41 to the delivery bands 43 and being passed by said bands to a's'uitable deposit receptacle or Llay-boy. 1

It is to be noted that they are thus caused to travel through a lengthy path and are at all times held in flat condition and against curling. Experience has demonstrated that with this structure but iew' cords are necessary-ordinarily three being suicent in thelower set thus obviating the danger of the Vcords striking the ruled lines and smearing the paper. Currents of air, either natural or artificial will also cause no displacement, and the work can consequently be artificially dried without danger ot mishap.

From the foregoing, it is thought that the construction, operation and many advantages o'lI the herein described" invention will be apparent to those skilled inthe art, with-` out further description, and it will be understood that various changes in the size, shape,

proportion and minor details of construction, may be resorted to without departing from the spirit or sacrificing any ofthe advantagesV of the invention.
